Moral nihilism is the view that there are no moral facts or moral truths. It is the ontological component of moral error theory, which is the best-known and most comprehensive metaethical theory that involves moral nihilism. My main aim is to discuss some consequences of endorsing moral error theory or believing to some degree that moral error theory is true. In §2, I consider the implications for ordinary moral thought and discourse and the epistemological consequences for moral theorizing. In §3, (...) I consider a recent challenge, according to which moral judgments do not have the epistemic profile that moral error theory alleges. I shall argue in §3–5 that the challenge can be met and that there is evidence that moral error theory is in fact correct about the epistemic profile of moral judgments. (shrink)

Non-naturalist normative realists face an epistemological objection: They must explain how their preferred route of justification ensures a non-accidental connection between justified moral beliefs and the normative truths. One strategy for meeting this challenge begins by pointing out that we are semantically or conceptually competent in our use of the normative terms, and then argues that this competence guarantees the non-accidental truth of some of our first-order normative beliefs. In this paper, I argue against this strategy by illustrating that this (...) competence based strategy undermines the non-naturalist’s ability to capture the robustly normative content of our moral beliefs.

Controversy about the credibility of normative realism is endemic to contemporary metaethics. Some take realism to be “obviously, the default position,” while others, to put it mildly, do not., In the face of such persistent controversy, it can be valuable to step back from the myriad arguments for and against realism, and seek to understand the challenges that face this view in their deepest and most general form. This paper aims to achieve this deeper understanding with respect to a pair (...) of familiar challenges to normative realism in the philosophy of mind. (shrink)

Intuitionism and nihilism, according to nihilists, have key features in common: the same semantics and the same phenomenology. Intuitionism is the object of nihilism’s attack. The central charge nihilism lodges against intuitionism is that its nonnatural moral properties are queer. Here I’ll examine what ‘queer’ might mean in relation to the doctrines nihilism uses to support this charge. My investigation reveals that nihilism’s queerness charge lacks substance and resembles a tautology served with a frown. There’s really nothing to it. After (...) I show that, I’ll offer an explanation for why nihilism has gotten intuitionism wrong. It makes a central mistaken methodological assumption and doesn’t target any identifiable intuitionism in the last hundred or so years. (shrink)

Ethical realists hold that our ethical concepts, thoughts, and claims are in the business of representing ethical reality, by representing evaluative or normative properties and facts as aspects of reality, and that such representations are at least sometimes accurate. Non-naturalist realists add the further claim that ethical properties and facts are ultimately non-natural, though they are nonetheless worldly. My aim is threefold: to elucidate the sort of representation involved in ethical evaluation on realist views; to clarify what exactly is represented (...) and how non-naturalism comes into the picture for non-naturalists; and to defend worldly non-naturalism against some objections. The first question addressed is how we should model evaluation on any realist view, which should in turn guide the identification of which properties and facts are credibly regarded as ‘evaluative’ ones. Then the question is: what role might non-natural properties and facts play, and how are they related to what is represented in ethical evaluation? Once that is clear, we will be in a position to answer certain objections to non-naturalist realism from Jackson, Gibbard, Bedke, and Dreier. I argue that the objections all mischaracterize the role played by non-natural properties and facts on plausible versions of non-naturalist realism. (shrink)

This paper responds to a recently popular objection to non-naturalist, robust moral realism. The objection is that moral realism is morally objectionable, because realists are committed to taking evidence about the distribution of non-natural properties to be relevant to their first-order moral commitments. I argue that such objections fail. The moral realist is indeed committed to conditionals such as “If there are no non-natural properties, then no action is wrong.” But the realist is not committed to using this conditional in (...) a modus-ponens inference upon coming to believe its antecedent. Placing the discussion in a wider epistemological discussion—here, that of “junk-knowledge”, and of how background knowledge determines the relevance of purported evidence—shows that this objection does not exert a price from the realist.

Are non-natural properties worth caring about? I consider two objections to metaethical non-naturalism. According to the intelligibility objection, it would be positively unintelligible to care about non-natural properties that float free from the causal fabric of the cosmos. According to the ethical idlers objection, there is no compelling motivation to posit non-natural normative properties because the natural properties suffice to provide us with reasons. In both cases, I argue, the objection stems from misunderstanding the role that non-natural properties play in (...) the non-naturalist's understanding of normativity. The role of non-natural properties is not to be responded to, but to "mark" which natural properties it is correct for us to respond to in certain ways. (shrink)

Non-naturalists face a dilemma. They either leave their normative views hostage to a non-natural realm, which is immoral, or they do not, which is irrational. David Enoch has argued that the problem rests on cases of junk knowledge — conditionals that cannot be used to expand knowledge via modus ponens. Camil Golub has suggested that the dilemma rests on questionable assumptions about how we might come to know about the non-natural. Here I reply to these worries, sharpen the dilemma, and (...) situate it in the literature on doxastic wrongs. (shrink)

Either 1. the non-naturalist is in a state of mind that would treat as relevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters, or 2. the non-naturalist is in a state of mind that would treat as irrelevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters. The first state of mind is morally objectionable, for one should (...) not change one’s normative beliefs to pander to the patterns of some non-natural realm. The second state of mind is irrational, for if you think you are aiming to represent non-natural properties correctly, you should be interested to know which actions share a non-natural property and which do not, and you should be prepared to change your mind accordingly.

Moral error theorists argue that moral thought and discourse are systematically in error, and that nothing is, or can ever be, morally permissible, required or forbidden. I begin by discussing how error theorists arrive at this conclusion. I then argue that if we accept a moral error theory, we cannot escape a pressing problem – what should we do next, metaethically speaking? I call this problem the ‘what now?’ problem, or WNP for short. I discuss the attempts others have made (...) to respond to the WNP, and in each case I show that the responses fail to be satisfying. I then propose a new response to the WNP, which I call revolutionary relativism. I define revolutionary relativism, explain why it is preferable to the existing responses to the WNP, and defend it against the most problematic objections I anticipate that opponents might raise. I conclude that revolutionary relativism succeeds where previous WNP responses fail, and that if we accept a moral error theory, we should become revolutionary relativists. (shrink)
